We have worked together with the gynecological departments at the universities of Leipzig and Dresden in conducting medical studies on a total of 158 infertility patients. Our studies have provided new medical findings on ovulation and variation in the menstrual cycle (Alexander 2015/Regidor 2017) from the 470 menstrual cycles evaluated.

We found that almost 70% of women ovulated outside the expected time window (day 14) despite a healthy biphasic pattern. The new findings have demonstrated the variability in menstrual cycles, and that every woman is unique in her fertility pattern.

Core body temperature serves as an indirect endocrinological biomarker in a variety of application areas in gynecology. These especially include diagnostics in an individual menstrual cycle by identifying the day of ovulation and fertile phase toward optimizing conception, treatment during in-vitro fertilization, and support for safe hormone-free contraception. Current studies are currently examining whether core body temperature might also contribute to determining risks such as miscarriage and other pregnancy disorders during early pregnancy.
